  If your Alinco Tuner won't turn on, there are several potential causes. First, check that the + and – polarities of the power connection are correctly connected. The red lead and the black lead of the DC power cable should be connected to the appropriate terminals. Second, verify the fuse isn't blown; if it is, address the reason for the blown fuse and replace it with a new fuse of the same rating. Finally, ensure that the power supply or DC/DC converter is turned on.

Why no sound comes from Alinco Tuner speaker?
- D
  Danny SalazarAug 8, 2025
  If no sound is coming from the Alinco Tuner's speaker and the unit isn't receiving, consider these possibilities: * The audio level may be too low, so adjust the volume knob. * The squelch may be muted, so decrease the squelch level. * Tone or DCS squelch might be active, so turn them off. * The PTT key of the microphone may be pressed for transmission, so release the PTT switch. * The external speaker could be defective, so remove and inspect it.

  If rotating the dial on your Alinco Tuner doesn't change the memory channel, it could be due to a couple of reasons. First, no memory channels may be programmed, so you should program memory channels. Second, the unit might be in CALL mode, so press the V/M key to cancel CALL mode.

  If pressing the UP/DOWN key on your Alinco Tuner does not change frequencies or memory channels, it could be because the unit is in CALL mode. Press the V/M key to cancel CALL mode. Another possibility is that the lock switch on the microphone is ON, so turn off the lock switch on the microphone.
